To all?!) h om it may concern I Befit known that we, HENRY Misrion and LEONIDAS "MANSELL, citizens of the United States, residing at West 'Enfield,v in

the county of Penobscot, State ofMai ne, have 'inventedcertainnew and useful Improvements'in Self-Propelled Sleighs; and

fwedo'hereby declare the, following to be a full, clear, and'exact description ofthe inventionfsuch as'willenable others skilled in the art to "whichit appertains to make and use the sameiq i i i 1 This 'inventi n relates to a self-propelled sleigh. An object of the invention resides in the provision of a, device of this character wherein the propelling will be accomplished within itself and wherein the shock incident to the riding of therunner's'over' uneven ground will betaken up before being'trans-J' 'mitted to the body of the sleigh. V

A further object of the invention resides in so constructing the device that the exhaust from the engine will be located soas to prevent the freezing of the operating parts or the clogging of them by snow or ice. With these and other objects in view, such as will appear as the description progresses, our inventioncomprises the combination and arrangement of parts as set forth in and falling within the "scope of the appended claim. 7 t Y Referring to the drawing: Figure 1 is a plan view of a sleigh'constructed in accordance with ourinvention.

Fig; 2 is a side elevation thereof. Fig. 3 is a fragmental side elevation of the propelling mechanism with the near rear runner and drive wheel casing removed.

Fig. 4 is a vertical sectional view on line 4-4 of Fig. 1, with the casings of the pro-' pelling wheel removed. r Fig. 5 is a vertical sectional view on line 55 of Fig. 1, showing the manner of mounting the rear runners. V Fig. 6 is a vertical sectional view of one of the bearing members for the runners. Fig. 7 is ahorizontal sectional view of the same.

Fig. 8 is a section taken at right angles to Fig.7, and likewise in a vertical plane."

Fig. 9 is a side elevation of one of the casings with thecovering cap removed and. the end of the spindle in section, showing the manner in which the spindle is mounted.

Referring tothe drawing wherein like I parts are indicated by "like characters throughout the: several vieWs:

- Our device comprlses a hasslslon which mounted. The rear end of this chassis/is I supported by runners. 2 in" a manner now to be described." :1 f-' Secured tov the rear axle 3 at each end thereof 'i s a pronged wheel 4 whichhas an outwardly extending: hub This hub 'ex-' tends into a'casingb which issecured to the adjacent-runnenat 7 and is rotatablewith relation thereto and also has vertical movement with'relation tothe casing. This hub extends into a-block 8 which terminates at its lower end in'a wedge-9. The end ofthis' hub 5 bears against ball-bearings 10 located in a'chamb'er in theblock'8. The end of-the axle is extended through the block 8 and is engaged by a nut 11 in a slot'12 ofthe 0&5. 7

casing 6 and are pressed inwardly normally.

toward each other to engage the wedgeshaped end of the block 8 by coil springs 17.

'The forward end of the chassis is supported "by suitable runners 18 which are mounted on the frontaxlel9 by bearings 20 which preferably include the shockabsorb- 1 ing device described in connection with the bearings for. the rearaxle. Thesefront runners are provided with a steeringrod 21 which may be operatedin any suitable manner. I I

Extending between the front ends of the rear runners and'the front ends of the front runners are rods 22 whichare made up of a plurality of sections joined together by universal joints 23. An'engine '24 is provided which has an exhaust pipe 25. This pipe is provided with divergingarms 26 which terand snow will be prevented from caking thereon. The propelling wheels 4. are provided'withlsuitable casings 27 to prevent the minate adjacent the casings 6 so'that'the same willlbe kept warm and consequently ice throwing of snow and ice "during the rotation of the same. The bottoms oftherunnersQ and 18 are provided with corrugations 28 to prevent skidding.

In operation as the runners pass over a rough road the shock incident to the movement Will be taken up because of the fact that the casings 6 Will slide upwardly on theblocks 8 and the sliding blocks 15 Will be separated against the tension of the springs 17;

The propelling heels 4c are provided. Wltll chambers 29 in Which suitable band brakes are locatedso that the rotation of the Wheels limay be prevented and-consequently a very effective brake provided. I

The tension of the springs 17 may be varied by means, of the adjusting screws 30 which operate against collars '31 and are in threaded-engagement with the chambers 16. Thus the spreading action of the blocks may 3e varied.

vWVhile We have illustrated andzdescribed a particular embodiment ofour nvention We haveimerely done sofor the sake of convenience and We donot ishto bevlimited to that particular embodiment as it is obvious that numerous changes may be made "in the details of construct-kin thereof Without in any Way departing from the spirit of Geples of this patent may beobtained'f or the invention or exceeding the scope of the appended claim.

What We claim isz+ V In a device of the class described, the combinati'on With a runner, an axle, a drive Wheel on said axle, a casing on said runner, a hub on said Wheel extending into saidcas ing, a hub block mounted for vertical movementin said casing and a i'evoluble support on said hub, the lower portion of said block ing and being beveled at their adjacent ends for. engagementjwith the opposite sides of said Wedge portion of. said hub blockgmeans for adjusting said blocks toward and. away from said hub block, and means for rotating five cents each, by addressing the Commissioner-pi manta Washington, D.
